BRAKE-EQUALIZER.

Specification of Letters Patent. Patented 001;, 31, 1911, Application filed June 29, 1911. Serial No. 635,938.

of the lever B. One of the brake rods is adapted to be pivo-tally connected with a I lever which forms a part of the brake mechanism of a four wheeled car-truck, as seen in Fig. 3 of my former patent. The other {brake rod IS similarly connected with the {brake mechanism of another truck, The keeper A, transverse lever B, rods C and the brake rods F perform the same function in the same manner as the similar members in the former patent.

My invention consists in the arrangement of the brake rods and their attachment on opposite sides of the lever B to the ends of improve upon and perfect that invention the bars D and E. The bars D and E serve and render the same more serviceable. as an extension of the brake rods. It will The weakness of my former invention lies be seen that if one of the brake rods, or one in the fact that if one of the brake rods of the bars D or the bars E are broken, the is broken or a part of the brake disabled opposite side, that is, the other brake rod the brake upon both trucks becomes useless. and the bars D connected thereto, will In this invention I have so constructed and strai hten out, the connected bars D serving arranged the different parts that the brake onlyioklengthen the brake rod, and only the on each side or on each truck will act unless part connected with one truck will become that part of the brake attachment is broken inoperative. It is necessary if both sides disabled, as will be hereinafter more fully become inoperative that the brake rods both ex lained. break or both pairs of the bars D or the le- I have illustrated my inventio pin the acver A be broken. The equalization of the companying drawing in which e figure is action of the brakes on each truck is attained a perspective view of the equalizing brake in the same manner as before and the operattachment, the rods connecting the equalation simplified.

In the construction of my improvement izer to the operating devices and the brake mechanism being broken off. stock material may be used and none of the In the drawing the slotted or bifurcated parts need be forged.

bar A is the keeper corresponding to the A forked rod G is pivoted to the lever B same member in my former patent, the same at one side of the center, the opposite end of being secured to the under side of the car the rod being secured to a spiral spring H,

in my former patent, or to other devices for Having described my invention, what I claim as new and desire to secure by Letmovlng them lengthwise to operate the brake. Double arallel bars D are pivoted to and inolose t e transverse lever B near ters Patent, is-

its ends at b and on opposite sides of the 1. An equalizing brake attachment, conlever, and the opposite ends of the bars D sisting of a transverse lever, pivoted cenare pivotally connected at c to the parallel trally, rods ivoted to the ends of said lever bars E between the ends of the latter. The I and adapted bars E extend over and under the keeper A for operating the brakes, brake rods extendand lever B and lie normally between the ing in o posite directions to the brake mechangles formed by the keeper and lever. anlsm, ars D pivotally connected to the Brake rods F are pivotally connected with brake rods at one end and to the transverse the bars D and E at their junction between lever at the op osite ends near the ends of the ends of the former and on opposite sides the transverse ever and on opposite sldes To all whom it may concern:

Be it known that I, HENRY LEWIS BLUNCK, a citizen of the United States, residing at Sioux City, in the county of Woodbury and State of Iowa, have invented certain new and useful Improvements in Brake- Equalizers, of which the following is a specification.

y invention relates to brake attachments and is an improvement upon the invention for which Letters Patent of the United States No. 977,998 were issued to me on December 6th 1910. i The object of this invention is to further to be connected with devices thereof, connecting bars E ivotelly secured at each end to the ends at the brake rods and the bars D at their junction, the bars 1) and connecting bars forming an extension of the brake rods connecting them with the lever, and a spring connecting the lever with the car body, substantially as described.

2. The combination in a brake equalizer, of a transverse lever ivoted centrally beneath a car body, brafie rods extending in onoosite directions to the brake mechanism, bars D pivotally connected to the brake rods and to the transverse lever near its ends on opposite sides thereof, and connecting bars E pivotally secured to the brake rods and to the bars D at the junction thereof, said bars D and connecting bars forming an extension of the brake rods connectin the rods to the transverse lever, substantia ly as described.

In testimony whereof I have hereunto signed my name in the presence of two subscribing Witnesses.

HENRY LEWIS BLUNOK.
